Parameter list
PNU Description
P230 Setting period of speed controller integrator
After a positive edge at the binector set in P695, the integrator of the speed
FDS
controller is set to the instantaneous value of the connector set in P631.
If a time of > 0 is set on P230, this setting operation is not performed just
(G152)
once, but the speed controller integrator is set continually to the setting
value for the parameterized time period.
P234 Set speed controller P component to zero
*
0 Set controller P component to zero (i.e. to obtain a pure I
FDS
controller)
(G152)
1 Controller P component is active
P236 Specifying the dynamic response of the speed control loop
*
FDS
The parameter value is used as the optimization criterion for the speed
control loop.
Note:
Changes to this value do not take effect until the speed controller
optimization run (P051 = 26, see Section 7.5) has been executed.
Setting instructions:
For drives, for example, with gear backlash, optimization should be
-
started with low dynamic response values (from 10%).
For drives with top synchronism and dynamic response requirements,
-
values up to 100% should be used.
11.13 Closed-loop field current control, field gating unit
P250 Alpha G limit (field)
FDS
Rectifier stability limit for firing angle of field converter
(G166)
P251 Alpha W limit (field)
FDS
Inverter stability limit for firing angle of field converter
(G166)
P252 Filtering of line frequency correction (field)
*
The internal line synchronization for the field gating pulses derived from the
FDS
field mains infeed terminals is filtered with this time constant. In operation
on "weak" power supplies with unstable frequencies, for example, on a
(G166)
diesel-driven generator (isolated operation), the filter time constant must be
set lower than for operation on "constant V/Hz" systems in order to achieve
a higher frequency correction speed.
Using the units position, the line synchronization function can be altered
additionally as follows:
When the parameter is set to an uneven number, the measured line zero
crossings for line synchronization are subjected to an extra "filter", may
improve performance in the case of difficulties with brief mains interruptions
(e.g. power supply via sliding current collectors), but may only be set for
constant V/Hz power supplies (not for weak isolated supply systems).
P253 Control word for field precontrol
*
0 Field precontrol disabled, precontrol output = 180°
FDS
1 Field precontrol active, output is dependent on field current
(G166)
setpoint, field line voltage, P112
P254 Set field current controller I component to zero
*
0 Set controller I component to zero (i.e. to obtain pure P
FDS
controller)
(G166)
1 Controller I component is active
P255 Field current controller P gain
FDS This parameter is set automatically during the optimization run for precontrol
(G166) and current controller (armature and field) (P051=25).
P256 Field current controller reset time
FDS This parameter is set automatically during the optimization run for precontrol
(G166) and current controller (armature and field) (P051=25).
